Numerous Rules for Dungeons & Dragons fall outside of the scope of what is necessary to play the game. Below you'll find information and rules to help customize the game, including information about the Planes of Existence in the standard Cosmology of the game world, rules for special options to empower your player characters, and more.
Here in you will find, collected in a single place, the various hacks and alterations that can be made to the game that are presented throughout this wiki. This collection serves to be a one stop shop for these specialized rules in case you need to reference them, but also an aid for the discussion you should be having with your players during Session Zero, when you're attempting to determine what changes, if any, you wish to make to the gameplay at the campaign's outset.
Sometimes player characters have something a little extra about them. A power or a trait that makes them greater than those around them, even above and beyond having levels in a Character Class. In the Magic the Gathering setting, Theros, this comes in the form of Heroic Gifts. In Ravenloft, characters can be granted Dark Gifts—or have them forced upon them by circumstance. In other cases a character's belief in their deity, their Piety, might be so strong it manifests in substantive, mechanical ways, even if they are not Paladins or Clerics.
